  • Thread-topic: mptsas driver failing in Xen-3.4 unstable version

On Xen-3.4 (unstable version), I have created CentOS PV guest and dedicated 
1068 SAS controller but I am not able to see the disk which is connected to 
1068 SAS controller when I do fdisk –l (vtd support is enabled in Xen).

Looks like the pci device(SAS controller) is getting dedicated successfully as 
I can see the device in the list of pci devices shown by lspci.

05:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express 
Fusion-MPT SAS (rev 08)

However the driver is not getting attached properly and fails with the 
following error

Fusion MPT SAS Host driver 3.04.05
                PCI: Enabling device 0000:05:00.0 (0000 -> 0003)
                mptbase: ioc0: ERROR - Unable to map adapter memory!
                mptsas: probe of 0000:05:00.0 failed with error -22

Any clues??
